Wren - Take Flight & Write

Writing Instrument of the Year 2025, Stationery Awards, London

A beautiful and infinitely refillable writing pen, equipped with a Japanese-made writing tip. We're on a mission to make choosing refillable options easier, so you can now buy two (or more!) Wren pens and save 10%

Each year, an estimated 9 billion pens are thrown away, contributing to growing environmental waste. Many writing tools are designed with convenience in mind, often leading to a cycle of frequent replacements, which generates significant waste and limits options for those seeking more sustainable, long-lasting choices.

As a product designer and craftsman who loves writing, I became frustrated with the waste created by disposable pens. They would pile up in drawers, waiting for a specific refill, or worse, end up in the bin despite being perfectly usable – if only they had ink.

After years of designing and handcrafting calligraphy and fountain pens for creatives worldwide, I decided it was time to tackle one of the biggest culprits: the everyday writing pen. The result? The Wren – a pen designed not only to write beautifully but also to last a lifetime, helping to reduce the mountains of waste created by disposable pens.

Included in the box:

  • The Wren in your choice of colour
  • Japanese-made Writing Tip*
  • 3ml Midnight Ink sample
  • Ink Reservoir

*0.3–0.5 depending on pressure

Specifications:

  • Length capped – 80mm
  • Posted (cap on the end of the pen) – 120mm
  • Pen barrel diameter – 13mm
  • Weight – 20g
  • Made from Anodised Aluminium

Full FAQs and a video guide to getting started with your Wren can be found here.

What ink can I use?
The Wren is compatible with all standard Fountain Pen Inks and we have a beautiful range of colours, which are perfect for the Wren and can be found here. Please note the Wren is not suitable for use with our Shimmer Fountain Pen Inks, No.60 Pigment Black Ink or Calligraphy Inks.

Some ink colours can concentrate in the tip, so you may experience a lighter colour after a line or two. This is completely normal and looks quite nice!

How do I store the reservoir and tips?
You can store reservoirs and tips, and change to a different colour using spare reservoirs and my reservoir storage containers.

How long will the tips/ink last?
You can expect the high-quality, Japanese-made tip to last for months of use. We tested a single ink fill in the Wren on a plotter – a device used for precision drawing – and it wrote consistently for 344 metres. That's the equivalent of 50 A4 pages of handwriting!

When the tip eventually dulls, you can find packs of three replacement tips here.

Anything else I should know?
Yes! I’ve designed the pen to include ‘micro-grooves’, tiny ridges that enhance grip without using plastics. Please note: the black and midnight colourways do not feature these micro-grooves, as they have a grippy matte finish.

Another beautiful pen to add to my Tom's Studio collection! The Wren might look small but it is a mighty powerhouse of a pen - light, easy to load with ink and writes better than any ballpoint pen I've used. Thanks Tom for creating another winner!

Its so cute

I absolutely LOVE this pen, I have had it since May, and I have used it every single day, I prefer it over my Lumos, its just such a cute size, and feels so comfortable to write with! My only wish would be you could buy a clip on clip, so you can attach it to things, just to make it easier to keep with my diaries/notebooks. The colour options are amazing, and I love that I can have the colours I want and not have to just have single boring colours. I just love everything about this little pen, just changed the nib for the first time, it was still working fine, but had just got a bit wider from being used, with me being a bit heavy with my hand. I just love everything about it!

Betcha can't have just one

I ordered a lovely Raspberry/Midnight Wren, determined not to lose it on my black desk—and then at lunch bought a black/black at an art supply store. I haven't regretted it: having one or two pocketable pens—my shirts have no pockets for an ordinary pen—means that using notebooks becomes practical, and I fuss with my phone—and get distracted—far less. I love the feel of writing with these. I have to admit that Tom's Fibre-Tip Ink does flow more readily than Tom's Fountain Pen ink does: with the two pens, it's easy to see and feel the difference.
These were just the gateway drug: now I have Tom's Pocket Fountain Pen, too, and have upped my taste in papers. I still use all three, every day.

Oh my, how I love this pen. I was a little unsure whether to order initially as I knew it was small, but goodness me I'm glad I did. What a powerhouse of a pen. A small, but perfectly formed maestro of a writing implement. Aside from the fact that I love that you can choose the colour combinations, and the ink is easily refillable. This pen writes like a dream. I want to sit and compose endless letters for the sheer enjoyment of using this pen. No regrets, only wondrous joy of finding a pen that writes so beautifully.
